WebAug 30, 2024 · The true value of measured resistance is Rm = R+Ra. To get exact resistance, the ammeter resistance must be zero. This is true in the ideal case. In the second configuration, connect the voltmeter in parallel with the unknown resistance. The voltmeter measures the correct voltage. WebJul 27, 2024 · How Do Multimeters Measure Resistance? The basics are simple: the meter supplies a fixed current to the resistance and measures the voltage across it. See Figure 2. Ohm's law: voltage equals current times resistance (V = I x R). Switching the range changes the current—higher for low resistances. The meter scales the reading to show ohms.
